Car not starting

i have a 1993 cadillac eldorado 4.9. i was driving down the road the other day and my car just stopped running. all my lights were still on so i know its not because of the battery. but i checked the battery anyways and it tested good. all signs pointed to the fuel pump. so i changed the fuel pump yesterday and my car still wont start. it turns over sounds like its about to start but never does. ive changed the spark plugs and wires, egr valve, all my air hoses around the TB.
im at work right now so im in a hurry with this message. let me know if ive left something out or if you need more information. ive ran the trouble codes and nothing has came up.

Re: Car not starting

I assume you changed the fuel filter when you changed the pump. Did you throw a gauge on it after the pump change to see what you have for pressure on the fuel rail? If everything checks out there, check for spark. It could be electrical problem.

Re: Car not starting

ive replace the ignition control module before. its not having the signs of that going bad. i believe. my problem might be my distrubtor its self. i took the spark wire off the distributor cap and tried to start it and didnt see any kind of spark going from the distributor to the wire. ive tried putting gas or carb fluid in the throttle body and it still wont start.

^^That IS a sign of a bad ignition module! I had an aftermarket piece from autozone and it lasted less than a year. Also check if you have 12v at the B+ terminal on the coil while the ignition is on. Be aware that if the module is bad, the computer wont fire the injectors - this could mislead you into thinking it's a fuel problem when it's likely a no-spark problem.

Re: Car not starting

yeah i remember it going out in 2007 and it would get hot and the car wouldnt start. and it got progessivly worse but would start as soon as the chip cooled off. and it never just died while i was driving just when i turned it off and tried starting it again would the problem occur. this symtom happened last winter so i changed the part thinking that it was the control module but it wasnt. it was the spark plugs and wires. but there is a possibility that i didnt put enough of that "stuff" down so the chip may have burnt up again. the "stuff" im talking about is the gooey stuff that you put on the chip. i remember being in a hurry changing it. the only reason i didnt think of the control module being the problem is because it died while i was driving. im going to go home when i get off work and look at the chip. is there anyway just by looking to see if the module is bad? like burnt looking?

Re: Car not starting

ok. and ive been talking to a mechanic that lives down the road. he thinks that since its a cadillac when i installed my fuel pump i have to enter in a code or something to get my car to recognize the fuel pump. is that true at all? i figured my manuel would have said something or the fuel pump directions would have said something about it?

.... Stay away from that mechanic, he doesn't know anything about Cadillac.... Do you have a FSM, your year and model there are 2 books. At times like these, it is invaluable.You will never get the injectors to work until you get spark. Speed sensor is in the distributor, AKA hall effect switch..
